ELAN Technologies and GMI Composites introduce a unique and innovative solution for wireless communications with underground utilities: a composite manhole cover with integrated antenna system. The manhole antenna cover system is designed and built to support secure, rugged, industrial wireless communications typically found in harsh underground utility environments. The system is designed to support today’s modern communication networks and includes worldwide frequency support for off-the-shelf wireless communication equipment.

Construction:
The cover is made of a unique composite material, designed to be lightweight and able to meet the AASHTO H-20 traffic rated requirements supporting up to 100,000 lbs. The GMI composite cover is fabricated to the shape and size that is required (round, square, rectangular) and can be provided with or without a manhole frame. GMI Composite Covers are corrosion resistant and can withstand water, salt water, sewer environments and petroleum products. GMI composite covers are non-conductive, shielding electricity, heat and steam from pedestrians above.
